Vientiane, Lao PDR, 1st Apr 2007 - 30th Apr 2007
When it comes to giant river prawns, it seems farmers want an all male world in their ponds, as they have discovered that the chaps grow big and strong if there are no females to put them off their stride. So in Viet Nam researchers have been busy under the microscope performing sex-change surgery on males to turn them into females. These neo-females are producing only male offspring which, in turn, are growing faster than those in mixed company. There is still a long way to go with the research but the prospects are bright.
